Summary: Enables GTPase activator activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in positive regulation of axonogenesis and small GTPase-mediated signal transduction. Located in cytoplasm and membrane. Is expressed in several structures, including cartilage; central nervous system; genitourinary system; liver; and respiratory system. Orthologous to human TIAM2 (TIAM Rac1 associated GEF 2).

Tiam2 is expressed in two isoforms, the full-length (Tiam2l) and a short transcript (Tiam2s). Tiam2s expression from the t-allele is strongly increased compared to the wild-type allele. By transgenic approaches we show that Tiam2s enhances t-haplotype transmission, while Tiam2l has the opposite effect.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
